Hi,

From time to time when switch on my PC I got black monitor with a message "Attention: No video input". It doesn't happen all the time: sometimes everything works OK. I noticed that usually it happens after the PC was switched off for a half day at least. Then I switch it on and off number of times and it finally starts to work.

What is wrong? How can I fix it?

Thanks in advance.

The monitor is not recieving any signal from the video card. If the card is not seated properly, no signal will be sent from the video card. Try reseating the card. Check that all pins are straight and connections are firm. With the lid off the PC check that the fan on the video is working properly if it has one. You can do this by starting the PC and a quick look will tell you. Shut the PC down and put the lid back on.

Thanks True Blue. It looks like my fan has problems. Now I put a big non-PC fun, directed it into open PC and my PC works. I'm going to replace my fan today and I'll write if it solved the problem.

I replaced the fan, but it didn't help. So finally I took it to PC technician and he told that there's a problem with my motherboard. (I hope he didn't cheat me). He replaced the motherboard and now it works OK.
